636.2 is the Dewey decimal number for cows, so I'm not sure how Millie Jane's diary ended up there.

I found this comic difficult to follow. I'm not a very visual person so maybe I just needed to look closer at the panels. Or maybe some DC back knowledge is necessary. All my Batman knowledge comes from the movies.

I did like the diverse cast though. I might check out the next volume if my library gets it in.
